2019-12-7 20:26:27 3323 网络音频上位机

0 电子可以一边玩，一边研究，网络音频这个课题特别适合电子爱好者。几方面的挑战如下，单片机实现对接以太网、实时对音频流解码播放，上位机配合单片机做音频流传输控制，音频信号的对接放大处理。在这里分享下资料，自己把这些关键威廉希尔官方网站整理下。原理图 PCB 上位机实物单片机关键程序 #include "STM32f10x.h" #include "usart1.h" #include "Systick.h" #include "vs1053.h" #include "ch395.h" #include "sdio_sdcard.h" #include "ff.h" #include "diskio.h" #include #include #include "timer.h" u8 ch395_T_Buffer="play over";
